Palladium Nanoparticle Catalyzed Conversion of Iron Nanoparticles into Diameter- and Length-Controlled Fe₂P Nanorods

Playing a dual role as a catalyst that destabilizes Fe nanoparticles to form soluble precursors in situ and as a catalytic center for nanorod growth allows Pd nanoparticles to transform Fe nanoparticles and a P source into Fe2P nanorods (see scheme). The diameter and length of the Fe2P nanorods can...

Zusammenfassung:Playing a dual role as a catalyst that destabilizes Fe nanoparticles to form soluble precursors in situ and as a catalytic center for nanorod growth allows Pd nanoparticles to transform Fe nanoparticles and a P source into Fe2P nanorods (see scheme). The diameter and length of the Fe2P nanorods can be fine‐tuned by means of the diameter of the Pd nanoparticles and the Fe/Pd ratio, respectively.
